摘　　要：为充分挖掘创新主体在网络中的位置对创新产出的影响,并探究地理临近性在其中是否发挥调节作用,本文以中国碳纳米管领域专利为例,从动态演化角度采用负二项回归分析方法进行实证分析。研究结果表明结构洞对创新产出有显著的正向促进作用,中心度对创新产出的影响呈现倒U型关系,当创新主体中心度过大时,会对创新产出产生抑制作;地理临近性与中心度的交互作用正向调节创新产出,地理临近性与结构洞的交互作用对创新产出的调节作用不显著。本研究对创新主体合作伙伴选择以及自我管理有重要的启示作用,创新主体要考虑自身在合作网络中的位置以及与合作伙伴的地理临近性。For exploiting the impact of network location on innovation output, and exploring whether the geographic proximity plays a role of regulation, in this paper, an empirical analysis was did with the method of negative binomial regression from the perspective of dynamic evolution, based on Chinese patent in the field of carbon nanotube. Results shows that structure holes have a significant positive impact on innovation output; the point centrality has inverted u-shaped relationship with innovation output; when the point centrality is over large, it will have an inhibitory effect on innovation output; geographic proximity and point centrality positively regulates the innovation output; the interaction of the geographical approaches and structural holes on innovation output was not significant. This research has important enlightenment on choosing partners and self-management for innovative main body which means that network location and geographic proximity need to be considered.
